Hello,
The KVM HV host module doesn't work anymore since the PowerPC updates
6.13-1 [1] and PowerPC MM updates [2].
We have tested it with our FSL P5020/P5040 boards [3].
The guest kernel doesn't boot. There is no output via the serial
connection and no output via the graphics card. (QEMU)
It boots without the PowerPC updates 6.13-1 [1] and PowerPC MM
updates [2].
Is the problem already known? Is there already a solution? I have
seen many Book3S KVM HV updates. Have you perhaps forgotten Book3E?
Thanks,
Christian

I tried to bisect but without success. Link:

It seems, that the PowerPC updates 6.13-1 aren't responsible for this
issue. I had to test the PowerPC updates 6.13-1 during the bisect. [1]
Bisecting: 428 revisions left to test after this (roughly 9 steps)
[42d9e8b7ccddee75989283cf7477305cfe3776ff] Merge tag 'powerpc-6.13-1' of

Result: git bisect good
There aren't any changes in the PowerPC MM updates [2].
Do you have another idea? I like KVM HV on my FSL P5040 system and use
it very often for testing. However, KVM HV is hardly used by our users,
so we could remove it from our kernels if it were not fixed. It would
save space to remove it.
